[Elecraft] OT - WSJT-X & K3s

I certainly do not blame the WSJT-x developers for not supporting serial port splitting products – they can be a nightmare. Their very reasonable policy is “if you can get it working by yourself, good for you. But don’t come to us looking for help.”

However, I respectfully disagree that there is no reliable solution. There have been no shortage of issues with Virtual Serial Ports on Windows with their dependence upon interrupt and event timing. I took a different route, developing a shared serial port that “outsources” serial port management to a Raspberry Pi. This avoids all of the issues in Windows, provides better performance due to caching, and presents less load on the K3 than from multiple individual devices.

I asked about this on the Yahoo WSJT-X group:

>From one of the developers,

"Hi Wes,

we do not support serial port splitting products with WSJT-X, they are 
unreliable as there is no acceptable way to divide control of a single device 
without arbitration. If you get it working then that's fine but don't expect it 
to stay working.

What is your logging program and SDR console? There might be a better solution.
